甲状旁腺的微囊肿(microscopic cysts)常见,但囊肿大到足以产生临床症状者却罕见。偶遇1例,报道如下: 患者,男,37岁。一年多前左颈部出现蚕豆大小肿物,渐大。半年来渐感说活时喉部不适。诊为“左甲状腺瘤囊性变”入院。检查:颈部相当于甲状左下极部位有一鸭蛋大小之肿物,皮肤色泽正常,肿物无压痛,触之囊性感,随吞咽上下移动。入院后行左侧甲状腺次全切除术,术中见囊肿位于左甲状腺下极部位,一个大囊有6×4×3cm大小,旁有3～4个小泡状囊,正常甲状腺组织已被挤压成很小一片。囊与甲状腺组织交界部可见棕黄色“脂肪样”小团粒,疑为甲状旁腺,小心分离保留之,将大囊完整 Parathyroid microscopic cysts are common, but cysts large enough to produce clinical symptoms are rare. In 1 case, the report was as follows: Patient, male, 37 years old. More than a year ago, the size of the faba bean mass appeared in the left neck and gradually became larger. Over the past six months, I gradually felt that my throat was unwell. He was admitted to the hospital as a “cystic lesion of left thyroid tumor”. Examination: The neck is equivalent to a duck-egg-sized mass at the lower left of the thyroid. The skin has normal color and no tenderness in the mass. The touch of the bladder is sexy and moves up and down with swallowing. After admission, a subtotal thyroidectomy was performed. During the operation, the cyst was located in the lower part of the left thyroid gland. A large capsule was 6×4×3 cm in size with 3 to 4 vesicles next to it. Normal thyroid tissue had been squeezed. Press into a small one. The vesicles and thyroid tissue can be seen at the junction of brown yellow “fat-like” small aggregates, suspected parathyroid glands, carefully separated and retained, the big bag intact
